Not only they got a reduction from statutory 35% down to 21%, but thanks to stock-based compensation and other tax benefits the main ndx companies are paying well below 21%. (Msft and Aapl look like close to pay near statutory tax rate anyway).

So, let me understand: Trump makes a gift to corporate America, runs trillions in deficit, companies find also several loopholes and come to pay 11% tax on average.
How do we call that? Subsidizing as well?

In some cases billions thrown to companies for the promise of creating jobs (unkept promises, see Tesla with its solar business for instance).
